The Major Stages of Urine Formation

Question 1

The first stage of urine formation is

Answer 1

glomerular
filtration

Question 2

After stage one, the final urine components are created through

Answer 2

tubular secretion

Question 3

tubular secretion

Answer 3

where wastes are put into the renal filtrate.

Question 4

tubular
reabsorption

Answer 4

desired materials are brought out of the renal filtrate back into the blood through

Question 5

The filtration membrane of the renal corpuscle is composed of

Answer 5

3 layers
a. the
filtration pores
of the capillaries of the glomerulus

b. the basement membranes of the glomerulus

c. the filtration
slits of the podocytes of the Bowman’s capsule

Question 6

Substances that normally pass through during filtration are

Answer 6

small
water, ions, glucose, amino acids, fatty acids, urea, creatinine, H+, etc

Question 7

Substances that normally dont pass through during filtration are

Answer 7

large
blood cells, plasma proteins, large anions, hormones.

Question 8

Most nutrients, like glucose, fatty acids, and amino acids will be

Answer 8

reabsorbed before urine is excreted

Question 9

The main pressure in the renal corpuscle that favors filtration is

Answer 9

glomerular blood
hydrostatic
pressure.

Question 10

The pressure inside the Bowman’s capsule that acts against filtration is

Answer 10

capsular hydrostatic pressure.

Question 11

The pressure of the proteins in the blood that opposes filtration at the renal corpuscle is

Answer 11

blood colloid osmotic
pressure.
